if you still happy with ListView then you can take idea from below
code
here i am using Cursor but you can use ArrayList in place of Cursor
public class Custom_Adapter_Products extends BaseAdapter {
Context context;
Cursor mCursor;
static int[] intArr;
DatabaseAdapter db;
public ImageLoader imageLoader;
public Custom_Adapter_Products(Context context, Cursor mCursor){
this.context = context;
this.mCursor = mCursor;
this.intArr = new int[this.mCursor.getCount()];
imageLoader=new ImageLoader(context);
}
#Override
public int getCount() {
return mCursor.getCount();
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
try{
ViewHolder holder;
this.mCursor.moveToPosition(position);
LayoutInflater vi = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
{
convertView = vi.inflate(R.layout.lv_row_for_products, null);
holder = createViewHolder(convertView);
convertView.setTag(holder);
holder.btnMinus.setTag(holder);
holder.btnAdd.setTag(holder);
}
else
{
holder = (ViewHolder) convertView.getTag();
}
holder.btnMinus.setOnClickListener(new OnClickListener() {
#Override

try{
ViewHolder holder = (ViewHolder) v.getTag();
// Do whatever you want
}catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
}
});
}catch (Exception e){
// TODO: handle exception
e.printStackTrace();
}
return convertView;
}
private static class ViewHolder
{
public TextView tvProductName;
public TextView tvPrice;
public TextView tvMRP;
public TextView tvMOQ;
public TextView tvPercent;

Use an AlarmManager with your specified time and the moment alarm will trigger you can enable the button, hence enabling the click event for the button.
Edit:
Either you can go ahead with handler object and use handler.postDelayed() method or there itself you can create a Timer Object and schedule the timer task within that object and do the stuff.

Assuming that u know how to convert the time strings into timestamps,modify ur adapter like this:
public class Custom extends BaseAdapter {
Activity a;
ArrayList<Model> data;
public Custom(Activity a, ArrayList<Model> data) {
this.a = a;
this.data = data;
}
#Override
public int getCount() {
return data.size();
}
#Override
public Object getItem(int i) {
return data.get(i);
}
#Override
public long getItemId(int i) {
return i;
}
public class Viewholder {
TextView srno, name, intime;
Button end;
}
#Override
public View getView(final int i, View convertView, ViewGroup viewGroup) {
Viewholder viewholder = null;
if (convertView == null) {
viewholder = new Viewholder();
LayoutInflater li = a.getLayoutInflater();
convertView = li.inflate(R.layout.list_item, viewGroup, false);
viewholder.srno = (TextView) convertView.findViewById(R.id.cno);
viewholder.name = (TextView) convertView.findViewById(R.id.cname);
viewholder.intime = (TextView) convertView.findViewById(R.id.ctime);
viewholder.end = (Button) convertView.findViewById(R.id.cend);
convertView.setTag(viewholder);
}else {
viewholder=(Viewholder)convertView.getTag();
}
final Model model = data.get(i);
viewholder.srno.setText(valueOf(data.get(i).getNo()));
viewholder.name.setText(valueOf(data.get(i).getName()));
viewholder.intime.setText(valueOf(data.get(i).getIntime()));
final Runnable r = new Runnable() {
public void run() {
viewholder.end.setEnabled(true);
}
};
if(yourObjectTimestamp - currentTimeStamp > 20){ //this u need to do on ur own
viewholder.end.setEnabled(true); // I assumed u know how to convert times to timestamps
}else{
viewholder.end.setEnabled(false);
long timeDiffInMillis = yourObjectTimestamp - currentTimeStamp;
handler.postDelayed(r,timeDiffInMillis );
}
viewholder.end.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(a, data.get(i).getName()+" Exited", Toast.LENGTH_LONG).show();
}
});

I have seen many SO anwsers but none of them got working in my case saying to add
listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
Can anyone say me how to acheive this ?

For complex ListView item, you should do it by yourself. Just add boolean isSelected in your ItemDetails and then checkBox.setChecked(item.isSelected); in your getView() in ItemListBaseAdapter. Now when an item is clicked in ListView just change your the data in itemDetailsrrayList and call notifyDataSetChanged().

I have made my getView() method.Just make radio button instead of simple button.I Hope this helps.
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
View productListView = null;
productListView = convertView;
LayoutInflater inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (productListView == null)
productListView = inflater.inflate(R.layout.menu_productlist_list,
parent, false);
productListTitle = (TextView) productListView
.findViewById(R.id.productListTitle);
String title = menuProductListCollection.get(position).getPD_TITLE();
productListTitle.setText(title);
productListCategoryButton = (ImageButton) productListView
.findViewById(R.id.productListCategoryButton);
// Perform Button action on click of each row's button
productListCategoryButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
//do your stuff here
}
});
// Perform action on click of each row
productListView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
//do your stuff here
}
});
return productListView;
}

I think you should try both of this,
listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
And in xml file you need to add,
<ListView
...
android:choiceMode="singleChoice"
... />
Also add this in your radio-button's xml,
<RadioButton
...
android:clickable="false"
android:focusable="false"
... />
Make HashMap m and initialize it
for (HashMap<String, Object> m :list_data) //make data of this view should not be null (hide )
m.put("checked", false);
Now, setViewBinder to adapter
adapter.setViewBinder(new SimpleAdapter.ViewBinder()
{
public boolean setViewValue(View view, Object data, String textRepresentation)
{
if (data == null) //if 2nd line text is null, its textview should be hidden
{
view.setVisibility(View.GONE);
return true;
}
view.setVisibility(View.VISIBLE);
return false;
}
});
It will work like charm.

Have you tried,
removing l1.setItemsCanFocus(true); and simply using:
...
else {
showSplashScreen();
setContentView(R.layout.main);
final ListView l1 = (ListView) findViewById(android.R.id.list);
l1.setAdapter(new EfficientAdapter(this));
l1.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapter, View view, int position, long arg) {
Object listItem = l1.getItemAtPosition(position);
Log.v("MyApp", "get onItem Click position= " + position);
Toast.makeText(getApplicationContext(), listItem.toString(),Toast.LENGTH_SHORT).show();
Toast.makeText(getApplicationContext(), "Valid", Toast.LENGTH_SHORT).show();
}
});
}
and removing
convertView.setClickable(true);
convertView.setFocusableInTouchMode(true);
convertView.setFocusable(true);
and using it like:
public static class EfficientAdapter extends BaseAdapter {
private LayoutInflater mInflater;
public EfficientAdapter(Context context) {
mInflater = LayoutInflater.from(context);
}
public int getCount() {
return country.length;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.listview, null);
holder = new ViewHolder();
holder.text = (TextView) convertView.findViewById(R.id.TextView01);
holder.text2 = (TextView) convertView.findViewById(R.id.TextView02);
holder.text3 = (TextView) convertView.findViewById(R.id.TextView03);
holder.text4 = (TextView) convertView.findViewById(R.id.TextView04);
convertView.setTag(holder);
}
else {
holder = (ViewHolder) convertView.getTag();
}
holder.text.setText(curr[position]);
holder.text2.setText(country[position]);
holder.text3.setText(country[position]);
holder.text4.setText(country[position]);
return convertView;
}
static class ViewHolder {
TextView text4;
TextView text;
TextView text2;
TextView text3;
}
}
??
